You could also develop its character based on its experiences with the environment. If it has to struggle to find food in a certain area of Jurassic Park, it might become more resourceful and determined. It could start to explore new areas and develop a sense of curiosity about its surroundings.
Character development for the baby T - Rex can also come from its relationship with humans, if there are any in the fanfiction. If it's captured by humans for study and then released, it could develop a sense of wariness towards humans. Or, if a human helps it when it's injured, it might develop a positive view of some humans, which would be a significant change in its character considering its natural instincts.
One idea could be that the baby T - Rex is found alone by a group of friendly dinosaurs who decide to raise it. It could grow up with different values than its aggressive species usually has. For example, it might learn to communicate with other species in a non - threatening way.
The relationship can be developed through mutual need. For example, if the human is lost in the dinosaur's territory, the T - Rex could initially see the human as prey but then realize the human has some unique skills, like making fire or using tools. This could lead to a truce. Or if the T - Rex is injured, the human could use their medical knowledge (assuming some sort of knowledge transfer in the story) to help the T - Rex, and in return, the T - Rex protects the human from other threats.
Rex could also be given a long - term goal, like mastering a very difficult form of magic. His journey to achieve this goal would involve a lot of trial and error, self - discovery, and training. Along the way, he would meet new characters who would either help or hinder him, which would further shape his character.
The baby Indominus rex could be described as having small but sharp teeth, and its eyes might be a vivid yellow color. Its scales are still a bit soft and not as tough as an adult's, with a pattern that is a mix of dark and light shades, giving it a somewhat mottled look.
I'm not sure of specific 'rex and ahsoka baby fanfiction' titles off - hand. But you can try searching on fanfiction websites like Archive of Our Own. There are often many talented writers who come up with interesting stories about different Star Wars characters and their relationships, including ones that might involve this concept.
One common theme could be family. The idea of Rex and Ahsoka starting a family and raising a baby brings in elements of love, protection, and new beginnings. Another theme might be the challenges they face, like how their Jedi and Clone Trooper backgrounds might affect their parenting.
Give it unique behaviors. For example, if your T - rex is a bit more cautious than others, it will add depth to its character. Maybe it hesitates before attacking large prey.
A possible plot could be about a baby Indominus rex being found alone in the wild. A group of scientists discovers it and decides to take it in. They try to raise it in a controlled environment, but the baby Indominus rex has a wild and unpredictable nature that causes all sorts of chaos and challenges for the scientists.
There might be some small animals like squirrels or rabbits that are either friends or prey of the T Rex.
The baby's character can be developed through its interactions with the magical world around it. For instance, if it shows a great love for magical plants early on, it can grow into a character with a passion for Herbology. Also, its reactions to different magical creatures can shape its personality. If it's fearless around dangerous creatures, it might be a brave and adventurous character.
